What's a little tube bending and welding after a V12 transplant? With that firing order, equal length may be a bit of a challenge; lot's of collector cross overs required for that arrangment.
Hehe, here's the '67 Ferrari 312 F1 car with its crossover system. Imagine trying this if the exhaust ports were outboard instead of inboard:
I prefer the way Gurney did his '67 Eagle, with the classic 3 into 1. This works pretty well for the 12's firing order:
And here's the way Jay Esterer did his bimmer motor for his V12 Ultima:

Just a note. If you are looking at anything other than the stock electromotive coil assemblies I would look into a different ECU. I have looked into this before and even spoken with the guys at Electromotive. The TEC unit uses a hard coded coil firing/charging strategy that will not be compatible with LS type coil packs. It may work but you may have coil failures and other issues. I ran a TEC unit on my car for years and ended up going with a Haltech for the flexibility. The LS coils are some of the most powerful OEM coils on the market and if you dont like the way they look just do what GM did. Cover them up .
Blaine thanks for the tip, however I'm not going to use those EM coils, nor the Electromotive ECU (to the great disappointment of my builder) I've had an AEM on my Supra since 2003 and have had very good success with it, so I'll be putting the V2 AEM on this engine.
Just wish there were some nicer looking smart coils out there than the LSx's The MSD's are good looking, but at over $120 a pop x 12, they would get ridiculously expensive very quickly. I'm a big fan of COP's, but with this SOHC motor, the location of the plug wells and their depth just doesn't permit a clean COP installation, so CNP it is.
